Rihanna turned 30 on Tuesday, and the pop superstar commemorated her milestone birthday by showing her mom some love with a heartwarming message of gratitude.

The “Diamonds” singer took to Instagram on her b-day to share a cute throwback photo of herself as a baby, which she dedicated to her mom, Monica Fenty.

“10958 days ago @monica_fenty became a mother for the first time to her only daughter!” the singer wrote. “Today is just as much your birthday as it is mine! I love you mom!”

She also made sure to show her appreciation for the hard work and sacrifices that go into being a mom, writing, “Thank you for carrying me, birthing me, raising me, supporting me, teaching me, and loving me unconditionally! The woman I am today is because of everything that you are!”

“I thank God for perfectly hand picking you to be my mother when He sent my spirit to you! You are the greatest! Thank you!” she concluded in her sweet post.
